Our website provides a free, on-the-spot analysis of your diet, physical activities, and lifestyle choices. You can use all of our site's features without becoming part of our study. However, if you decide to enroll you will become part of an international study to test whether nutrition, physical activity, and traditional and alternative medicine prevent heart disease and cancer. Important scientific findings from our studies have been reported in the New England Journal of Medicine and elsewhere. Analyses will be supplied to you throughout the 35 minute questionnaire.

The information you provide will be held in confidential files. Your personal data will never be given to anyone else. No publication or other use of this information will in any way identify you as a participant. We will not become aware of your identity unless you click the "consent" button at the end of this questionnaire.
